Dale ... I am running the same set up as JB ... I got the Hyperion 4025-12 on Rhino 5S 4,900 mAh packs, a DualSky 60A ESC and turning a 16x10. The power set up is nice for pattern and not if you want to 3D. I got my CG nice with the set up, I still have a lot of space to move the pack fore or aft. My packs come down just starting to warm up only after a 6 min flight. I put back about 3,500 mAh.

I have some friends who run the Hyperion 4025-12 on an 80A ESC and they turn a 16x12 ... watch this video:

I find the Hyperion 4025 to be a really good combo. I did try the AXI 4120 and the DualSky 4260-6 (566KV) but they only are good for a 14x10-15x10. A 16"prop is really nice for the Angel.
